I got the stove installed just in time for the worst of the weather. I've been burning wood for the time being because that's what I have access to at the moment. I've been learning the stove and it's pretty consistent. I'm not used to burning wood and didn't know what to expect but I was surprised that the max burn time I can get is 5 hours and that's with the stove full and both dampers closed. It will hum along with a door temp of 300-350 degrees loaded up with dampers closed.
A buddy gave me a bag of Blaschak anthracite the other day and I threw in a few pounds last night on top of a good bed of coals then I stacked 4 logs over that, closed the dampers and went to bed. This morning, the wood was gone but the coal was still there and hot. I put on a layer of coal and a load of wood and she is still going strong. I an to burn straight coal once I have the time and money to get a load. As for now, I've just been trying to get an overnight burn and wood alone wasn't doing it but I think I've found a good combination. I wish I had enough anthracite to run it straight for a few days so I could see what the stove would do loaded up with the stuff. Anthracite is newer to me than wood, we burned bit coal back home so this is a learning experience.
One thing is for sure, this stove would be useless without a damper in the stove pipe. My chimney has such a strong draft and this is an older stove that is not airtight so I have to close both dampers to slow it down. Otherwise, it looks like a blast furnace, lol. Once the grate is completely covered with a bed of coals, the airflow is cut down and the stove is easier to regulate but this thing has a huge grate and it takes a while to build up enough coals to cover it.
